1. A device management apparatus comprising: memory storing computer-readable instructions; and a processor configured to execute the computer-readable instructions such that the processor is configured to, acquire event information of an electronic device in response to an event occurring in the electronic device, the device management apparatus and the electronic device being connected to a first network, notify a remote management apparatus of the event information so as to manage the event information together with the remote management apparatus, the remote management apparatus being connected to a second network, store, in storage of the device management apparatus, a correspondence relation in which each event of the electronic device is associated with first device-status information of the electronic device, first reference-destination information indicating a reference destination of the first device-status information, and second reference-destination information indicating a reference destination of second device-status information of the electronic device that is managed by the remote management device apparatus, switch, based on the correspondence relation, from an access to the first reference-destination information to an access to the second reference-destination information associated with the event occurring in the electronic device in response to accepting the access to the first reference-destination information from a first terminal on the first network before reference-inhibition instruction information indicating an instruction to inhibit reference to the first device-status information is acquired from the remote management apparatus, and inhibit the first terminal from accessing the first reference-destination information in response to acquiring the reference-inhibition instruction information from the remote management apparatus, based on the remote management apparatus accepting the access to the second reference-destination information from a second terminal on the second network, before the access to the first reference-destination information is accepted from the first terminal.
This invention relates to a device management system for electronic devices connected to different networks. The system includes a device management apparatus and a remote management apparatus, each connected to separate networks. The device management apparatus monitors events in an electronic device, stores event information, and notifies the remote management apparatus to coordinate management. The system maintains a correspondence relation linking each device event to device-status information, including local (first) and remote (second) reference destinations. When a first terminal on the first network requests access to local device-status information, the system switches the access to the remote reference destination if the remote management apparatus is already handling a request from a second terminal on the second network. If the remote management apparatus later issues a reference-inhibition instruction, the system blocks further access to the local device-status information. This ensures synchronized management and prevents conflicts when multiple terminals attempt to access device status from different networks. The system dynamically redirects access requests to maintain consistency and control over device information.
2. The device management apparatus according to claim 1 , wherein the processor is configured to execute the computer-readable instructions such that the processor is further configured to, output a request for acquiring the reference-inhibition instruction information from the remote management apparatus at an interval shorter than a communication interval at which polling the remote management apparatus is performed prior to acquiring the event information from the electronic device.

The problem addressed is the delay in receiving critical event notifications due to standard polling intervals, which can lead to inefficiencies in device management and response times. The apparatus includes a processor configured to execute instructions for managing electronic devices. A key feature is the ability to request reference-inhibition instruction information from a remote management apparatus at a shorter interval than the standard polling interval used before acquiring event information from the electronic device. This allows for more frequent checks for critical instructions or updates, reducing latency in receiving important commands or status changes. The processor also handles the acquisition of event information from the electronic device, ensuring timely updates on device status or events. By dynamically adjusting the polling interval for reference-inhibition instructions, the apparatus optimizes communication efficiency while ensuring critical information is received promptly. This approach minimizes delays in responding to device events or management instructions, improving overall system responsiveness and reliability. The invention is particularly useful in environments where real-time or near-real-time device management is required, such as industrial automation, IoT networks, or remote monitoring systems.
3. The device management apparatus according to claim 2 , wherein the processor is configured to execute the computer-readable instructions such that the processor is further configured to, update the first device-status information at the interval shorter than the communication interval.

The apparatus includes a processor that executes instructions to collect and manage device-status information from connected devices. The processor periodically updates this information at a communication interval to balance network traffic and data freshness. Additionally, the processor updates a subset of the device-status information, referred to as first device-status information, at a shorter interval than the communication interval. This allows critical or frequently changing device parameters to be monitored more frequently without increasing overall network load. The apparatus ensures efficient resource utilization while providing timely updates for essential device metrics, improving system responsiveness and reliability. The solution is particularly useful in environments where real-time monitoring of specific device parameters is necessary, such as industrial automation, IoT networks, or remote device management systems.
4. The device management apparatus according to claim 3 , wherein the processor is configured to execute the computer-readable instructions such that the processor is further configured to, stop outputting the request for acquiring the reference-inhibition instruction information from the remote management apparatus at the interval shorter than the communication interval in response to completing updating the first device-status information in accordance with the event information.
This invention relates to device management systems, specifically addressing the challenge of efficiently managing communication between a device management apparatus and a remote management apparatus to reduce unnecessary data transmission. The system includes a device management apparatus that periodically requests reference-inhibition instruction information from a remote management apparatus at a predefined communication interval. The apparatus monitors device status changes, such as events or updates, and updates its local device-status information accordingly. To optimize communication, the apparatus temporarily stops sending requests for reference-inhibition instruction information at intervals shorter than the predefined communication interval once it has completed updating the device-status information based on event data. This reduces redundant communication, conserving network resources and processing power. The system ensures that the device management apparatus only requests necessary updates, improving efficiency while maintaining accurate device status tracking. The invention is particularly useful in environments where multiple devices are managed remotely, such as in IoT networks or industrial automation systems, where minimizing unnecessary communication is critical for performance and scalability.
5. The device management apparatus according to claim 1 , wherein, the first reference-destination information includes a uniform resource locator (URL) of the device management apparatus, the second reference-destination information includes a URL of the remote management apparatus, and the second network is a different network from the first network.
A device management apparatus is designed to facilitate secure and efficient communication between a device management apparatus and a remote management apparatus across different networks. The apparatus addresses the challenge of managing devices in environments where direct communication between management systems is restricted due to network segmentation or security policies. The invention enables a device management apparatus to relay information to a remote management apparatus by using distinct reference-destination information for each system. Specifically, the first reference-destination information includes a URL of the device management apparatus, while the second reference-destination information includes a URL of the remote management apparatus. The communication occurs over two separate networks, ensuring that data can be transmitted even when the networks are isolated from one another. This setup allows for centralized management of devices while maintaining security and operational flexibility. The apparatus may also include a communication unit for transmitting and receiving data, a storage unit for storing reference-destination information, and a control unit for processing and relaying data between the two systems.

6. A device management method comprising: acquiring, by a device management apparatus, event information of an electronic device in response to an event occurring in the electronic device, the device management apparatus and the electronic device being connected to a first network; notifying, by the device management apparatus, a remote management apparatus of the event information so as to manage the event information together with the remote management apparatus, the remote management apparatus being connected to a second network; storing, in storage of the device management apparatus, a correspondence relation in which each event of the electronic device is associated with first device-status information of the electronic device, first reference-destination information indicating a reference destination of the first device-status information, and second reference-destination information indicating a reference destination of second device-status information of the electronic device that is managed by the remote management apparatus; switching, by the device management apparatus, based on the correspondence relation, from an access to the first reference-destination information to an access to the second reference-destination information associated with the event occurring in the electronic device in response to accepting the access to the first reference-destination information from a first terminal on the first network before reference-inhibition instruction information indicating an instruction to inhibit reference to the first device-status information is acquired from the remote management apparatus; and inhibiting, by the device management apparatus, the first terminal from accessing the first reference-destination information in response to acquiring the reference-inhibition instruction information from the remote management apparatus, based on the remote management apparatus accepting the access to the second reference-destination information from a second terminal on the second network, before the access to the first reference-destination information is accepted from the first terminal.
This invention relates to a device management system for electronic devices connected to a network, addressing the challenge of coordinating event management and status information access between local and remote management systems. The system includes a device management apparatus connected to a first network and a remote management apparatus connected to a second network. When an event occurs in an electronic device, the device management apparatus acquires event information and notifies the remote management apparatus to enable collaborative management. The device management apparatus stores a correspondence relation associating each device event with local device-status information, a reference destination for that local information, and a reference destination for remote device-status information managed by the remote management apparatus. When a first terminal on the first network requests access to the local reference destination, the device management apparatus switches the access to the remote reference destination based on the stored correspondence relation, provided no reference-inhibition instruction has been received from the remote management apparatus. If the remote management apparatus receives an access request from a second terminal on the second network, it may send a reference-inhibition instruction to the device management apparatus, which then prevents the first terminal from accessing the local reference destination. This ensures synchronized access control and prevents conflicts between local and remote management systems.
7. The device management method of claim 6 , further comprising: outputting, by the device management apparatus, a request for acquiring the reference-inhibition instruction information from the remote management apparatus at an interval shorter than a communication interval at which polling the remote management apparatus is performed prior to acquiring the event information from the electronic device.
This invention relates to device management systems, specifically improving the efficiency of communication between a device management apparatus and a remote management apparatus to handle event notifications from electronic devices. The problem addressed is the delay in receiving critical event information from electronic devices due to standard polling intervals, which can lead to missed or delayed responses to important events. The method involves a device management apparatus that periodically polls a remote management apparatus to retrieve event information from electronic devices. To enhance responsiveness, the apparatus sends a request to acquire reference-inhibition instruction information at a shorter interval than the standard polling interval. This allows the device management apparatus to quickly determine whether an event notification should be suppressed or processed, reducing latency in event handling. The reference-inhibition instruction information may include conditions or rules that dictate whether an event should be ignored or acted upon, ensuring more efficient resource utilization and timely responses to critical events. The method also includes steps for the device management apparatus to receive and process the reference-inhibition instruction information, enabling dynamic adjustment of event handling based on real-time conditions. This approach optimizes communication efficiency while maintaining system reliability, particularly in environments where timely event processing is essential. The invention is applicable in various device management scenarios, including IoT systems, industrial automation, and remote monitoring applications.
8. The device management method of claim 7 , further comprising: updating, by the device management apparatus, the first device-status information at the interval shorter than the communication interval.
The invention relates to device management systems, specifically addressing the challenge of efficiently monitoring and managing the status of multiple devices in a network. Traditional systems often rely on periodic communication to update device status, which can lead to delays in detecting changes or issues. This invention improves upon existing methods by implementing a more dynamic approach to status updates. The method involves a device management apparatus that communicates with multiple devices at a predefined communication interval to collect device-status information. However, to enhance responsiveness, the apparatus also updates the first device-status information at a shorter interval than the communication interval. This allows for more frequent monitoring of critical status parameters without increasing the overall communication load. The apparatus may prioritize certain devices or status parameters for more frequent updates based on predefined criteria, such as device importance or historical failure rates. Additionally, the apparatus can adjust the update interval dynamically in response to detected changes or anomalies, ensuring timely detection of issues while optimizing network resources. The method may also include filtering or aggregating status data to reduce redundancy and improve efficiency. This approach ensures that device management remains responsive and reliable, even in large-scale networks with numerous connected devices.
9. The device management method of claim 8 , further comprising: stopping, by the device management apparatus, the outputting the request for acquiring the reference-inhibition instruction information from the remote management apparatus at the interval shorter than the communication interval in response to completing updating the first device-status information in accordance with the event information.
This invention relates to device management systems, specifically methods for optimizing communication between a device management apparatus and a remote management apparatus to reduce unnecessary data transmission. The problem addressed is the inefficiency in conventional systems where device status updates are frequently requested, even when no significant changes have occurred, leading to wasted bandwidth and processing resources. The method involves a device management apparatus that periodically requests reference-inhibition instruction information from a remote management apparatus at a predefined communication interval. This information determines whether the device management apparatus should suppress status updates to the remote management apparatus. When an event occurs that triggers an update to the device's status information, the device management apparatus updates its local status data accordingly. Upon completing this update, the apparatus stops sending requests for reference-inhibition instruction information at intervals shorter than the predefined communication interval. This prevents redundant requests when the status has already been updated, conserving network and computational resources. The method ensures that status updates are only transmitted when necessary, improving system efficiency. The invention is particularly useful in environments where devices frequently generate status changes but do not always require immediate remote updates.
10. The device management method of claim 6 , wherein, the first reference-destination information includes a uniform resource locator (URL) of the device management apparatus, the second reference-destination information includes a URL of the remote management apparatus, and the second network is a different network from the first network.
This invention relates to a device management method for securely and efficiently managing devices across different networks. The method addresses the challenge of managing devices that may be connected to separate networks, such as a local network and a remote network, while ensuring secure communication between a device management apparatus and a remote management apparatus. The method involves generating first reference-destination information, which includes a URL of the device management apparatus, and second reference-destination information, which includes a URL of the remote management apparatus. These URLs are used to establish communication paths between the devices and the respective management apparatuses. The first network, where the device management apparatus operates, is distinct from the second network, where the remote management apparatus operates. This separation ensures that device management operations can be performed securely across different network environments. The method also includes transmitting the first and second reference-destination information to a device, allowing it to communicate with both the device management apparatus and the remote management apparatus. This enables centralized management of devices while maintaining secure connections across different networks. The invention improves device management efficiency by reducing the need for direct, unsecured communication between devices and remote management systems.
